| Abstract |
| Transverse strength of various shapes and si:::es of kaolin, sillimanite,
alumina and :::ircon test specimens. fired to ·z:arying temperature,
wa~ determined in an attempt to understand the si'gnificance
of 'stressed area' in such determi11ations. A large porti'on of the
test pieces roas subjected to a maximum bending moment by a twopoint
loading system for determining the transverse strength and
the trend of average results appeared to depend 011 the probability
of hafJing maximum stress at the 'most dangerous' jlafo, thus the
results showed an increase ~cith the decrease in length and diameter
or thickness of the test specimens. Tramverse strength of the
circular specimem was greater than that of the square specimem
of similar thickness possibly because the maximum stress in the
latter case acted on. an area rather than mz a line as in the case
of a circular specimen. The si:::es of thr. test specimens were so
choun that the rati'o of the span used for testing thickness of
specimen varied between 5 and 30. The experimental results of
any batch could not, |
